Additional tests including penetration,solubility, and ductility are made on the residue. Cutback asphalt grades and tests There are several grades for each of the three types ofcutbacks â rapid curing (RC), medium curing (MC), andslow curing, (SC). The grades include 70, 250, 800, and3000.
The surfacing of the asphalt is plant mix pavement (PMP) in the top lift of 1.4 inches (35mm) and PMP in the bottom lift of 5.2 inches (132mm). Asphalt temperatures are recorded at 18 different depths of the pavement between the surface and as deep as 25 inches (635mm).
